Clinical Profile of Pediatric Tuberculosis in a Tertiary Hospital in Northeast India: A Retrospective Analysis

Abstract

Context Tuberculosis (TB) is India’s major public health problem. The profile of childhood TB in the northeast region of India is still limited. Aim To analyze the clinical, radiological, and bacteriological profiles of children with TB at a tertiary health care facility. Materials and methods A three years retrospective descriptive analysis of children admitted to a tertiary centre with TB before the introduction of cartridge-based nucleic acid amplification test (CBNAAT) for testing. Children below 18 years who were admitted from 2012 to 2014 and were diagnosed with TB were included. Relevant data were extracted in a predesigned format and entered into a Microsoft Excel sheet. Descriptive statistic was used for analysis. The results of variables are given in proportions and means and a Chi-square test was done for the test of significance using Epi-info tools. The study was done after getting ethical approval from the institute. Results A total of 150 children were included in the analysis with a Male: Female ratio of 1.1:1. A majority of the cases were under five years (n=46) and 11 to 15 years old (n=45) with a mean age of 9.3 ± 4.4 years. Fever was a common presentation (70%). Disseminated TB was seen in 31.3%, isolated central nervous system (CNS) TB was found in 30.6%, and all CNS TB with dissemination was found in 46 cases (40.7%) making extra-pulmonary TB a common finding in our study (83.3%). Isolated pulmonary TB was seen in 16.7% and total pulmonary cases along with dissemination was seen in 60 cases (40%). A bacteriological diagnosis was made in 23%. Overall mortality was 9.3%, out of which mortality in CNS TB was 13% with a p-value of 0.004 as compared to mortality other than CNS TB which was significant and mortality in under-five years was significant with a p-value of 0.001. Conclusions Pulmonary and extra-pulmonary were both causes of admission in the pediatric age group. We found that extra-pulmonary TB was the most common cause of admission in children, with CNS manifestation and disseminated TB, being the most common presentations and significant mortality was seen in under-five years and in children diagnosed with CNS TB.
